A coordinated athlete who pivots out of his stance well, Petrus is very natural pulling around the line of scrimmage and reaching the second level. Possesses great body control and does a nice job breaking down in space and eliminating a moving target. Is a violent cut blocker who does a great job getting into opponents' bodies and eliminating them from the play. Showcases natural balance on slide-down blocks and makes it difficult for opposing defensive linemen to disengage. Displays the flexibility to drop his pad level in pass protection and gain initial leverage on contact. Relies on his technique and quickness in all areas of his game and lacks the overall girth and base strength to overpower defenders on contact. But Petrus looks like an ideal starting guard in a zone-blocking scheme at the next level.
